Various changes-and modifications in the arrangement'of parts of 'the door mechanism will be apparent tothose skilled in the art without departing from the scope of theappended claims.

Having thus described the invention," whatjI claim as new and desire tosecure by Letters Patent is:

. 1. In a dump car, an underframe, a tiltable 1 body, a door for said body and'hinged adjacent ;the floor, a member pivotally mounted on said door, amember pivotally mounted on: said body and connected to said door, member, cooperatingstop shoulders on said members limiting'rotation between said members in one direction and means mounted on said underframeand in engagement with both of said members for controlling rotaframe, a dump-body, a body pivot, a door forming a wall of saidbody'and hingedadjacent the fioorthereof, means connected to said door and to said body outwardly of the pivot for controlling the movements of said'door by movement of said body upon said pivot and for selectively :releasing said door for'movement in one direction independentv of said body.

3. In a dump car, an'underframe, a dump body, a door forming a wall for said body and hinged adjacent the floor thereof, a mechanism contr'olling the movements of said door through move-' mentof' said body relativeto the underframe,

said mechanism being pivotally connected to said body and door and comprising a member pivotally mounted on the underframe slidably connected with said mechanism.

4. In a dump car, in combination, an underframe, a tiltable body, a hinged door on the body, and a door controlling means, said means comprising a toggle member pivotally connected to the door and to the body and a member pivotally mounted on the underframe and having a bifurcated' portion spaced from the'underframe, with .said bifurcated portion embracing said toggle member. I I 5; In a dump car, the combination with a tiltably mounted body and a door hinged adjacent the'floor of the body, of a door gear comprising a' member pivoted to the door, a member pivoted to the body, and a member pivoted to the underframe, and a common connection between said members which moves relative to the underframe to control the opening and closing of the door as joint'and pivoting upon the underframe.

'7. In a dump vehicle, an underframe, a body supported directly upon the underframe, a pivotal connection between the body and underframe independent of the body supports, a door forming a wall of the body and hinged adjacent the floor thereof, a jointed member forming a compression lock between the door and body, and a link pivotally connected to said mechanism joint and underframe, said link moving relative to the underframe to control the opening and closing of the door as the body moves in dumping.
